IMPROVEMENT IN REVERSIBLE CURB-BRICKS.

Specification forming part of Letters Patent No. 134,994, dated January 21, 1873.

To all whom it may concern:

Be it known that I, EDWARD LINSON, of Shoemakertown, Montgomery county, Pennsylvania, have invented an Improved Curb- Brick, of which the following is a specification:

My invention consists in a reversible curbbrick for the curbs of carriage-roads and walks in parks, gardens, &c. A curb may be made of aseries of the improved bricks, each of which is of the form represented in the per' spective view, Figure 1, of the accompanying drawingthat is to say, so rounded at its upper and lower edges that there will be one flat side, I), of the full extent of the brick, and an opposite flat side, I), of less area, the brick being laid end to end, so as to form a continuous curb.

The advantage of a curb of this characteris the facility with which it can be laid in the manner illustrated in the vertical section, Fig. 2, where A represents the surface of the walk or roadway, B the sod, and D the intervening curb-brick.

It is an easy matter to cut a suitable trench for the reception of the bricks, owing to the rounded edges of the latter. Fig. 3, for instance, represents an appropriate trench, which can be dug much more readily than one fit to receive ordinary square-ended bricks.

In laying the bricks, the side having an extended flat surface is presented to the soft sod and earth, against which it is held by the harder material of the walk or roadway, which is compressed against the more limited flat surface b of the opposite side of the brick the latter is consequently retained firmly in its place.

The rounded upper edge of the curb will more efl'ectually resist the action of the wheels of vehicles without breaking than a sharp- Witnesses:
